The term "yunque" refers to an anvil, a heavy block of iron or steel used in metalworking. It provides a solid surface for shaping and forging metal objects, such as tools and horseshoes. The yunque is essential in blacksmithing, where heat is applied to metal to make it malleable. In some cultures, particularly in Puerto Rico, "yunque" also refers to El Yunque National Forest, a tropical rainforest known for its biodiversity and lush landscapes. This forest is home to various plant and animal species, making it a popular destination for nature lovers and hikers.
